Thoughts on the #amdflaws stuff: most of the attacks described appear to require some level of privileged access (and possibly physical access in one case), which will lead to people writing it off as entirely overhyped. This is a mistake.

So this https://t.co/vYktqat10K business… CTS Labs asked us to review their research last week, and sent us a full technical report with PoC exploit code for each set of bugs.

This! Vulns are overhyped, paper is garbage, authors are PR seeking clowns https://t.co/aXaKk13jiR

First read of the AMDFLAWS whitepaper (no real technical details given) is: “over-hyped beyond belief”.
This is a whitepaper worthy of an ICO.
And yes, that is meant to be an insult.

While vulns in PSP firmware are bad enough (impacts fTPM, SEV, BIOS secure boot), no one is asking why compromising PSP allows bypassing Win10 VSM (read “IOMMU”) and SMM (read “SMRAM memory controller protections”).

This likely indicates that PSP can modify memory map protections and IOMMU config

Most of AMD vulns from amdflaws has the same impact as any other SMM issues. The interesting one is code execution on Secure Processor. But looks like it's related to fTPM issue with the same impact (https://t.co/zlyAiPx0XJ). Also on ASUS hardware BIOS security is always broken.

Note: there will be no “second read” of the AMDFLAWS whitepaper because none is required.
It is a phishing document to lure small traders.

Folks, the CTS lawyers are out… “they are not statements of fact”.
So, are they vulnerabilities or not?
If they are not statements of fact they are fiction. https://t.co/KLyhvX5kvp
